APPARATUS FOR MAKING SALT.

SPECIFICATION forming part of Letters Patent No. 269,355, dated December '19, 1882.

' Application filed October 4, 1882. (No model.)

T all whom it may concern Be it known that I, CLEMENS VON BECH- TOL'sHElM, of Munich, in the Empire of Germany, have invented new and useful Improvements in Apparatus for Making Salt, of which the following is a specification.

The object of my invention is to provide a new and improved apparatus for concentration of brine and deriving the salt from the same.

The invention consists in the combination, with a, brine-boiler, ot' a device for receiving brine from the boiler and two evaporatingpans, one of which pans is connected with the boiler and a pumping-engine in such a manner that the steam from the pan, which is heated by direct flames, can be used to heat the brine in the boiler and to work the pumping-engine. From the boiler the brine passesinto the dome, and is then pumped into the two pans. The steam from the doineis used to heat one of the pans.

The invention also consists in parts of construction and combinations of the same, as will be fully described and set forth hereinafter.

Reference is to be had to the accompany ing drawing, forming part of this specification, in which a longitudinal sectional elevation of my improved brine concentrating apparatus is shown.

An evaporating-pan, A, which hasaV-shaped cross-section, is placed into and over a furnace, B, of some suitable construction, so that the pan can be thoroughly heated. The pan is provided with a cover, 0, made of wood, provided with side pieces which dip into the brine, and with an inner metal covering; or it can be made wholly of metal. Wedge-strips D are placed between the downwardly-projecting side pieces of the cover and the inner surface of the pan to prevent any steam from escaping through thejoint of the cover 0 and the pan; or, if desired, gate-strips a can be hinged to the lower edges of the side pieces of the cover, the free edges of the said gate-strips resting against the inner surfaces of the pan, as shown; or; any other suitable packing dedevices may be used to prevent the escape of steam. By means of a conveyer or some other suitable device in the bottom of the pan the salt is carried to one end of the pan, and is carried out of the same by means of an elevator or bucket chain-pump, J. A steam-pipe, E, leads from the top of the pan A to the boiler F, and a branch pipe, G, of the pipe E leads to the steam-engine H. The pipe E is provided with a cock, E. The boiler is provided with alarge central brine-tube, F, which is surrounded by a cylindrical steam space or jacket, F through which aseries of vertical tubes, F pass, in which brine can circulate. The condensation-water is carried off through a pipe, d. The brine is conducted into the boiler F by means of a pipe, 1, provided with a cock, f. The boiler is closed by means of a removable cover, g, which is closed by means of a water-seal. A tube, K, provided with agate, K, connects the upper part of the boiler F with a dome, L, which is provided with an outlet-pipe, M, for the brine, which pipe M leads to a pump, N. A steam -pipe, 0, extends through the dome L from near the top of the same to the steam-jacket P of an evaporating-pan, P, which can be flat or can have a V-shaped crosssection. The condensationwater and air in the steamackets P are withdrawn from the same through the pipes at and thy a pump, Q, which, with the pump N, is operated by the. engine H.

The condensation-water can be used to heat the brine before the sameis admitted into the boiler F. The pipe at is provided with acock, n. A pipe, It, leads from the pump N to the pans A and P. The exhaust-steam from the engine H passes into the pipe 0.

The operation is as follows: The brine is adinitted into the boiler 1 through the pipe I,

and is heated in the boiler by the steam, which enters the same from the pan A through the pipe E, which steam circulates around the tubes F and F The heated brine tlows through the tube K into the dome L, in which some of the water is converted into steam, which passes through the pipe 0 into the jackets P of the pan P. Thetemperature of said steam is about 75 Centigrade, (167 Fahrenheit.) The brine is drawn fromthe dome L by means of the pump N, and is forced through the pipe B into the pans A and P, in which it is thoroughly concentrated and evaporated to such an extent that the salt-crystals can be separated from the same. If the boiler F is to be cleaned the valve K is closed, the boiler is emptied, the normal atmospheric pressure is restored in the same, the cover 9 is removed, and the tubes F F are thoroughly cleaned. The cover is then replaced, and the boiler is again filled with brine, and the valve K is opened to establish communication between the boiler F and the dome L. The apparatus can be started immediately, as none of the vacuum has been destroyed. To produceavacuum before starting the apparatus the cocks f and a are opened. The steam then passes from the pan A to the boiler F, the dome L, the steam-jackets P, and escapes at the cock n. The steam heats all the parts through which it passes,'and if the cooks f and n are closed the condensation of the steam in the above-described parts produces the desired vacuum.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In an apparatus for concentrating brine, the. combination, with the brine-boiler F, of the dome L and the evaporating-pans A and P, substantially as herein shown and described, and lor the purpose set forth.

2. In an apparatus for concentrating brine, the combination, with the brine-boiler F. of the dome L, the evaporating-pans A and P, and the pump N, substantially as herein shown and described, and for the purpose set forth.

3. In an apparatus for concentrating brine, thec0mbiua\ion,with the brine'boilerRof the evaporating-pan P, provided with steam-jackets P, the dome L, and the steam-pipe 0, extending from the dome L to the jackets P, substantially as herein shown and described, and for the purpose set forth.

4. In an apparatus for concentrating brine,

thecombination, with the brine-boiler F, of the dome L, the evaporating-pans A and P, the

pump N, the pipe M, leading from the dome L to the pump, and the pipe R, leading from the pump to the pans A and P, substantially as herein shown and described, and for the purpose set forth.

5. In an apparatus for concentrating brine, the combination, with the brine-boiler-F, of the evaporating-pans A and I, the dome L, the steam-pipe 0, the pipes M and It, the pumps N and Q, and the pipes at and l, substantially as herein shown and described, and for the purpose set forth.

6. In an apparatus for concentrating brine, the combination, with the brine-boiler F.0f the evaporating-pan A andthe steam-pipe E, leading from the pan to the boiler, substantially as herein shown and described, and for the purpose set forth.

7. The combination, with a V-shaped evaporating-pan, ot' acover having side pieces dipping into the brine, and of packing-strips be' tween the side pieces of the cover and the sides of the pan, substantially as herein shown and described, and for the purpose set foith.

8. In an apparatus for concentrating brin thecombination,with the brine-boiler F, of the evaporating-pan A, the steam-pipe E, leading from the pan to the boiler, and the steam-pipe G, leading; to the pumping-engine H, substantially as herein shown and described, and for the purpose set forth.

In testimony whereof Ihave signed myname to this specification in the presence of two subscribing witneses.
